LANSING — Volunteers are being sought to assist with Michigan’s 16th annual frog and toad survey, which provides the Department of Natural Resources (DNR) with useful data on populations of amphibians.

Declining numbers of frogs, toads and other amphibians have been documented worldwide since the 1980s. Studies suggest amphibians are disappearing due to habitat loss, pollution, disease and collection.

Michigan’s annual survey efforts help biologists keep tabs on frog and toad abundance and distribution in the state.

“We have collected a large, valuable data set to help us evaluate the condition of Michigan’s frog and toad populations,” said Lori Sargent, the DNR’s survey coordinator, in a press release.

The surveys are conducted by volunteer observers along a statewide system of permanent survey routes, each consisting of 10 wetland sites. These sites are visited three times during the spring when frogs and toads are actively breeding. Observers listen for calling frogs and toads at each site, identify the species present and make an estimate of abundance.

“We need new volunteers in all parts of the state. Please consider joining us every spring for a fun, educational opportunity and run a route,” Sargent said. “The continued success of the program is dependent on strong volunteer support.”

Interested persons should contact Sargent by e-mail at sargentl@michigan.gov or phone at 517-373-9418.
